We're 'ath10k_snoc', not 'ath10k_pci'. This probably means we're accessing junk data in ath10k_snoc_rx_replenish_retry(), unless 'ath10k_snoc' and 'ath10k_pci' happen to have very similar struct layouts. Noticed by inspection. Fixes: d915105231ca ("ath10k: add hif rx methods for wcn3990") Signed-off-by: Brian Norris <briannorris@xxxxxxxxxxxx> --- It's possible this would be a for-4.18 target, since the buggy patch is in the -rc1 merge. But this driver is not fully operational yet. Also, I'm sending some companion refactorings to help avoid this bug. They probably aren't 4.18 material. Let me know if I should do anything differently. drivers/net/wireless/ath/ath10k/snoc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/wireless/ath/ath10k/snoc.c b/drivers/net/wireless/ath/ath10k/snoc.c index ee74e0060504..c7cfc9c9b3d7 100644 --- a/drivers/net/wireless/ath/ath10k/snoc.c +++ b/drivers/net/wireless/ath/ath10k/snoc.c @@ -449,7 +449,7 @@ static void ath10k_snoc_htt_rx_cb(struct ath10k_ce_pipe *ce_state) static void ath10k_snoc_rx_replenish_retry(struct timer_list *t) { - struct ath10k_pci *ar_snoc = from_timer(ar_snoc, t, rx_post_retry); + struct ath10k_snoc *ar_snoc = from_timer(ar_snoc, t, rx_post_retry); struct ath10k *ar = ar_snoc->ar; ath10k_snoc_rx_post(ar); -- 2.18.0.rc1.242.g61856ae69a-goog
